To all 'whom it 'may concern:

Be it known that I. WILLIAM M. GREEN, a citizen of the United States ot' America, and a resident ot' the city of Evanston, in the county of Cook and State of Illinois, have invented a certain new'and useful Improvenient in HydrocarbonBurners, of which the following is a specification.

My invention relates to compound burners in which the flame is supplied with a fluid or vaporized hydrocarbon compound. together with another fluid or gas which is either or both combustible or supportive of combustion. To the end, therefore, of thoroughly mixing the combined gases or Huid when presented to the flame. completely con-A trolling the properties of the mixture, and thereby producing more Complete and perfect combustion with its attendant increased economy and efficiency, I have invented the device herein described.

In the drawings-Figure 1 represents a vertical longitudinal section of a burner and controlling apparatus made in accordance with the principles .of my invention, and Fig. 2 is an alternative form of burner and cap.

As shown in Fig. l the burner proper consists of an external shell A, in the outer end of which is inserted by a, screw threaded attachment the disk B, having the central opening C. Inside the shell A is a nozzle D, having a'centrally perforated cap VE 'at the zouter extremity thereof. The nozzle may be mounted as shown at e so that it stands free for the whole of its length within the burner shell A. The external part 4of the cap E on the end of the nozzle is formed to a rounded or other suitable contour, and

the inner part of the cap B is formed to.

correspond therewith. The two by proper adjustments may be made to assume a close contact at any desired normal or other temperat-ure. Connection with a source of oil supply may be made `through the pipe rep- 'resented at F, sufficient pressure to force such length that at normal.temperature the needle valve and the globe valve should operate simultaneously. in the same relation to eachother. Steam or air under pressure may .be supplied to the apparatus from any suitable source of supply through the pipe I. The flow of such fluid is controlled bythe globe valve K through the valve seat Z'.

VAlfter passing therethrough the flow of fluid lmay be directly through the pipe L wherein the flow is checked and controlled by the cock Z, or through the pipe M in which the flow is checked and controlled by the cock in.

The shape of the ame depends largely on the distance between the 'internal and external portions of the disk B. resented in Fig. 1 the edges of the aperture C are very thin, and the distance between the two sides practically nothing. With this construction the flame will be very broad and fan shaped. But by the expedient shown in Fig. 2 the flame may be condensed or contracted. Instead 'ot' using a single As repdisk I provide two disks b and Z2 adapted for close contacten their facing sides. Both of the disks b and b are threaded on their outer edges so that they can be moved independently of each other. The outer disk b may be provided with ears b which may l liquid fuel is permitted through the cap E of the nozzle D. At the same time a iow of air or steam under pressure superior to that of the fuel, is permitted by opening the valve K, and its direction is controlled through the pipe L by closing the cook m and opening the cock Z. Being thus directed it surrounds the nozzle D within the jacket A and flows through a slight space produced by expansion at normal temperature between the inside of the cap D and the eX- terior of the cap E. This flow atomizes or vaporizes the oil or other fuel iuid, and, being ignited as it passes through the burner, combustion of thetwo takes place. The heat of such combustion being .communicated to the jacket A causes the same to exjacket will, therefore,

pand, while the flow of air or steam throu ha the jacket A keeps the nozzle D relative y cool.' The longitudinal expansion of they slight y increase the s ace between the disk B.y and cap E,-causin'g lt e flow of air or steam Vto be increased ,to

the end of making a more perfect combus-` tion.. As the heat of the chamber surround,-

ing the burner increases, as well as that of the burner itself, the fuel becomes more and more volatilized and disintegrated, and the increasing heat of the a paratus tends to extend this condition to t e portion of the fuel contained inthe pipe or chamber G. If the requirement for oxygen to support combustion becomes Greater the eiciency of Y. being stopped the nozzle D expands lo'ngitudinally, thus partially or quite, (as lts length is greater than that of the jacket A), closing the space between the disk B and ca E. In the use of various classes'of 1i ui fuel the relative flow of fuel and com ustion su porting fluid through the differentl channe s may be varied to-advantage. The iow of fuel may be confined to the chamber G and the combustion supporting fluid to the pi e L. Both may bemade to flow as descri ed through the chamber G, or by manipulation of the cocks and valves, the
